Unless the engineer that designed this and configured your firewall is
an idiot, this will be difficult at best. Most times he firewall is
configured to accept connections on the inside from the proxy and only
from the proxy (or other priveledged host). You might be able to spoof
the proxy address, but again its a long shot at best.
